The document outlines various software development methodologies, including Agile, Scrum, Cleanroom, Lean, Extreme Programming (XP), Feature Driven Development (FDD), Test Driven Development (TDD), Rational Unified Process (RUP), and the Dual Vee Model. It emphasizes the iterative and incremental approaches, flexibility in development, and principles aimed at improving software quality and responsiveness to customer needs. Additionally, it mentions specific frameworks and practices associated with each methodology.

2. What is Software Development Methodology ?
 It is the framework used to plan, control and structure the
process of developing the information system.
 Software Development is considered a subset of the systems
development life cycle.
 It includes the pre-definition of deliverables, artifacts created
and completed by a project team for development or
maintenance of the application.

4. • Group of software development
methods
• Based on iterative and incremental
development
• Most important phrases
• self-organizing, cross-functional teams
• adaptive planning,
• evolutionary development and delivery,
• a time-boxed iterative approach,
• rapid and flexible response to change.
• A conceptual framework
Agile

5. • Scrum is an iterative and incremental agile software development framework
• It is a flexible, holistic product development strategy and opposite to sequential approach.
• In it the Development team works as an atomic unit

6. • The Cleanroom process embeds software
development and testing within a statistical
quality control framework.
• Mathematically-based software
development processes are employed to
create software that is correct by design,
and statistical usage testing processes are
employed to provide inferences about
software reliability.
• This systematic process of assessing and
controlling software quality during
development permits certification of
software fitness for use at delivery.

7.  It is a translation of lean manufacturing
principles and practices
 For e.g. Toyota Production System,
 Today it is a part of Agile community.

8. 1. Eliminate waste
2. Amplify learning
3. Decide as late as possible
4. Deliver as fast as possible
5. Empower the team

9. • It improves software quality and responsiveness to changing customer requirements.
• It has frequent "releases" in short development cycles.
• Introduce checkpoints where new customer requirements can be adopted.

10.  Iterative and incremental development
process.
 An Agile method
 Driven from a client-valued functionality
(feature) perspective
 Mostly part of other methodologies
Feature Driven Model (FDD)

11.  Relies on the repetition of a very short development cycle: first the developer writes an
(initially failing) automated test case that defines a desired improvement or new function,
then produces the minimum amount of code to pass that test, and finally refactors the new
code to acceptable standards.
• Test-first programming concept of extreme programming in the beginning
• Today standalone methodology

12. • An iterative software development process framework created by the Rational Software
Corporation (IBM)
• Not a concrete prescriptive process, but an adaptable framework, intended to be tailored
by the development organizations
• It is expected to select elements of the process that are appropriate.
Rational Unified Process (RUP)

13. • It describes a model of complex
development
• For example:
• Hardware
• Platform
• Application software
• Development of a system's architecture is
the “Big V”
• Components’/entities’ developments are
the “small V”-s
• It shows interactions and sequences of
developing a complex system and a system
of systems.
